Patented Jan. 8, 1907.

Application filed July 20, 1906. Serial No. 327,016.

To all whom, t may concern:

Be it known that I, CHAUNCEY D. BRADT, a citizen ofthe United States, residing at Troy, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Machines for Cutting Paper, Cardboard, or other Stock, of which the following is a specification.

My invention relates to machines for cutting paper; and the object of my invention is to rovide a means for feeding the paper or card to the cutters whereby the position `of the paper or card in reference to the knife may be adjusted and` redetermined, with means for changing tfie adjustment, and such other elements and combinations as are hereinafter more particularly specified and claimed. I attain these objects by means of the mechanism illustratedin the accompanying drawings, in which- Figure 1 is a front elevation with cutterbar removed. Fig. 2 is a plan. Fig. 3 is a section along the lines X X on Fig. 2. Fig. 4 is an enlarged front elevation with parts broken away, showing the feed and scale. an enlarged elevation of the gear and pinion. Fig. 6, Sheet 4, is a side elevation of the crank. Fig. 7, Sheet 1, is an elevation of a modified form of casing. Fig. 8, Sheet 4, is a section along the line X2 X2 on Fig. 4. Fig. 9 is a section along the line X3 X3 on Fig. 8. Fig. 10, Sheet 2, is a perspective view of one end of the clamp-plate and guide-post; Fig. 11, Sheet 1, an elevation of the guidepost Fig. 12, the nut for the guide-post 5 Fig. 13, an elevation of a taper pin; Fig. 14, a plan of taper pin; Fig. 15, Sheet 3, a perspective view of detachable portion of clamp; Fig. 16, Sheet 2, a erspective view of the rear clamp. Fig. 17, S eet 3, is a detail sectional view with parts broken away, showing the position of the clamp 4 in connection with clampbar C4. A

Similar letters and 4numerals refer to similar parts throughout the several views.

For the purpose of cutting paper or pasteboard a table, knife, and screw for causing the back gage to move forward toward the knife have heretofore been used. In order to cut narrow strips of paper which may be used for displaying the different colors of paint when said strips are colored, A(said strips for designating the color of paint placed in pails or packages usually indicated y numbers and said strips attached to folders or boards or display-cards for the purpose tween the end of the of enabling a customerv to select by color of the paint that he wishes,) I have arranged a means for regulating the feed ofthe cutting-machine and adjusting same so that the stock placed on the bed of the cuttingmachine may be brought forward by the operator to exactly the desired positionwithout requiring attention upon his part to see the position to which he moves the crank-handle governing the screw and back gage.

The shaft S carries a screw-thread s and is mounted beneath a table T. A nut U is placed on thethreaded portion s of the shaft S and is connected, bymeans of the bolt u, with the back gage V. The shaft S carries a pinion' P thereon, which meshes with the gear seeing the G on the shaft H and to which shaft H is keyed the ratchet-wheel J. I preferably place an annular groove h in the shaft H, to which the dog K engages, and nearer to the end of the shaft H, I place a series of holes k,

. in which the dog K may project when it is desired to key the crank L to the shaft H. Loosely mounted on the shaft H, I place the crank L, which is provided with a handle M, preferably near one end, and a sleeve l, which is'placed upon shaft H. Adjacent to the handle M on the crank L, I preferably place a disk N, the disk being attached to or formed integral with the sleeve n, which has at its end farthest from the disk a shoulder n', which engages one end of a spiral spring m.

The other end of said spring engages a shoulder a, ofthe stop-bolt A, there beingl opportunity for the movement of the hand e M beshoulder n and the end of the handle, the bolt A, passing through the handle M, being secured by nut A lor any other suitable manner to the end of the handle. As thus arranged the spring m will forcethe bolt A forward by moving the handle M upon the sleeve n of the crank L, as shown in Fig. 6. The bolt will be withdrawn by moving the handle M to the position shown in Fig. 3. A j

The bolt A will act as a stop for the crank ICO L when it projects from the-crank. When the bolt A is drawn into the crank, it will pass the projection against which it would engage were it acting as a stop. I also arrange on the crank L a stop-bolt B, which is preferably arranged nearer the end of the cranky than the stop-bolt A, as shown in Fig. 3, and preferably has an inclined working face adapted to pass the permanent stop C3, Fig. 4, when moved in one direction, but to .en-

' Staa H,

gage the same when moving in the opposite direction, and which has a spring b, engaging a shoulder in the shank of the bolt and the seat of the recess in which the bolt is housed within the crank L, tending to project the bolt beyond the face of the crank, as shown in Fig. 3. I also preferably arrange a screw b in the end of the crank L, which engages the groove b2 in the side of the bolt B and holds the bolt in position.

Crank-sleeve Z, which is mounted upon the as aforesaid, carries the dog K, which is in the form of a lever pivoted to the sleeve and preferably having a spring Z, which tends to keep the opposite end of the lever or dog in engagement with the shaft H by projecting it into the annular groove h or within one of theholes 7c in said shaft, depending upon the position of the crank-sleeve thereon. The crank L also carries near its end opposite the stop-bolts A and B the dog F, adapted to engage the ratchet-wheel J and is preferably provided with a spring f, resting against one side of the dog F, tending to keep said dog in engagement with the teeth of said ratchet-wheel, as shown in Fig. 4, and as thus arranged it will be seen that as the operator rotates the crank it will cause the shaft H to rotate, which will set in motion the screwshaft 'S and move forward the back gage V. The 'opposite rotary movement of the crank L may be made without moving the ratchetwheel, because the dog F will ride loosely over the tee-th thereof. When it is desired to move the back gage toward the rear of the machine, I place the dog K in engagement with one of the holes vlc in the shaft H and then rotate the crank to the left, which will, because the crank is shaft H, rotate the screw so as to move the back gage toward the rear.

For the purpose of limiting the extent of the rotation ofthe screw-shaft, and therefore the forward movement of the back gage, and

ofpaper to be cut, I provide, preferably, one stop D, which may be formed upon the stopwheel C', which fits within the case C, which case is mounted to the under side of the table T by bolt c or in any suitable manner and through which case the shaft H passes.

The position of the stop-wheel within the case C is regulated as to its rotatable position in said case by means of the regulating-bolts C2. I preferably graduate both the case C and the stop-wheel C', as shown in Fig. 4, for the purpose of enabling me to determine the position in which the stop-wheel, should be placed within said case, since it is necessary to arrange for having the stop on the stopwheel located in proper position by means of the clamping-bolts C2, so that the stop-bolts will engage the same at the proper degree of rotation of the screw Sto make the strip of paper to be cut of the desired width.

then attached to the l a series of guide-posts therefore provide for the width of the strips i with an enlarged opening 3, with I have shown in Fig. 7 a modified form of the face of the case C, placing therein a series of rounded openings c, Within which I may place the taper pins 9, Fig. 14, instead of using the stop-wheel. Of course I do not limit myself to the shape of the opening c nor to their position on the face of the case C.

For the purpose of securing the various piles of paper one arranged on top of the other upon the table T of the machine I place at the rear of the machine a back gage V, which, as hereinbefore stated, is moved. by the rotation of the screw S, and to the front of the back gage V, I arrange a clamping device by means of which the rear ends of the paper may be held securely together. The clamping device consists of a rail IV, which rests upon the table and which is provided with an upwardly-extending plateVV, secured to the back gage V byscrew V', or in any suitablemanner. Thevertical plateWis provided with a projecting flange W 2, extending along the front or face from one end to the other, and l upon the end of the vertical plate W a series of blocks Y are mounted, the blocks Y being provided with an opening Y, which nts upon the end of the vertical plate VV, which open- -ing Y is so constructed as to conform with.

the flange W2 bein@ rovided with a wall e e p which iits beneath said flange, as shown in n Fig. 3. Through the block Y the clamp bolt Y? is screwed. The blocks Y l eing movable upon the plate W may be placed in any desired position, and clamp-bolt Y2 may be screwed down in contact nth the paper placed on the horizontal rail W. A clamping device attached to the back gage is particularly desirable when the paper on the table is made up of several p-les of narrow strips, and each clamp-bolt Y2 may engage one of said piles.

For the purpose of guiding the paper at its end farthest from the back gage I arrange Z, which are provided with a threaded projection z at one end, adapted to extend through a slot 10 in the clamp-plate 2. (See Fig. 10.) A bolt c may be threaded on the projection z beneath said slot 10. The clamp-plate 2 is provided which sai d slot 10 connects and through which. the bolt z may pass after being attached to the projection e. The guide-posts Z may thus be placed in such position as is desired along the slot l0, as shown in Fig. 2, and I preferably place a slot Z2 on top of the guide-posts Z to secure same to the clamp-plate.

It is sometimes desirable to arrange my machine for cutting ordinary stock which eX- tends across the whole table instead of being divided into narrow strips. To do that, I mayincrease the bearing-surface of the stockretain-ing device by placing the clamp 4, which is preferably provided with a series of openings 5, into which the projections of the TCC IOS

IIO

ISC

back gage V enter after the rail W has been removed. The end of the clamp 4-. is preferably provided with a tongue 6, which engages with a groove in the clamp-bar C4. (See Fig. 17.) I place a knife 7 as shown in Fig. 3, which may be brought in contact with the stock placed on the table.
